As promised, Jolla has shown off its newly launched Sailfish OS today, and said that UI will be all about speed and multitasking, while also cutting down on the finger dancing required to use it. The experience will start from the homescreen, where users will be able to control music playback or end a call using a "pulley" menu system without needing to open the respective apps. The Finnish startup also said that "many" Android apps would run on Sailfish handsets without modification, though a simple port would be required for best operation. Jolla foresees the software running not only smartphones from hardware players like new partner ST-Ericsson, but also tablets, smart TVs and in-car systems, for instance.
